Alien plants

Abstract

The catalogue accompanying this paper includes all those members of the Tasmanian Flora which come under Hewett C. Watson's designation of Aliens. This is a happily conceived title, first instituted by that veteran botanist; and it was intended by him to embrace such species as have been introduced either by accident or design, and which have maintained their ground more or less firmly in their adopted country. I also include a few plants which, in Mr. Watson's more extended vocabulary, would probably be named by him waifs, strays, and casuals; but the number of these is so small that I have thought it better to bring them all under the general designation of Aliens.
